World Cup in Qatar to use semi-automated offside system

FIFA has confirmed that a semi-automated offside system will be used at this year's football World Cup in Qatar. The new technology utilises a limb-tracking camera system to track player movements and a sensor in the ball. It then quickly shows 3D images on stadium screens at the tournament to help fans understand the referee's call. It is the third World Cup in a dispute that will see FIFA introduce new technology to help referees. The optical tracking system was trialled at the FIFA Club World Cup in Abu Dhabi earlier this year and had also been tested at the Arab Cup in Qatar last December.
